Watch Sing 2 (2021): Where to Stream the Animated Musical in 4K

If you want to watch Sing 2 with the whole family, you are in for one of the most colorful, music-packed animated movies of recent years. The 2021 sequel takes everything audiences loved about the original and turns the volume way up, sending Buster Moon and his troupe of singing animals on a bigger, bolder adventure. Below you will find a spoiler-free premise, why the film is worth your time, and exactly how to enjoy Sing 2 streaming in stunning 4K with InfinityTV.

What is Sing 2?

Sing 2 is an animated musical comedy and the follow-up to the 2016 hit Sing. It reunites the lovable cast of performers from Buster Moon's theater as they set their sights on something far grander than a local stage. Bursting with pop hits, dazzling choreography, and heartfelt character moments, it is a feel-good film built for viewers of every age.

The movie blends laugh-out-loud comedy with genuine emotion, wrapping its lessons about courage and perseverance in showstopping musical numbers. It is the kind of family film that keeps kids glued to the screen while giving adults plenty to enjoy too.

A quick recap of the first Sing

Before diving into Sing 2, it is worth understanding where the story came from. The original Sing, released in 2016 by Illumination Entertainment, introduced Buster Moon, a koala and aspiring theater impresario whose beloved Moon Theater is on the verge of bankruptcy. In desperation he stages a singing competition to save the venue, attracting a cast of unlikely local performers: a pig named Rosita who has put her own musical dreams on hold to raise her enormous family, a gorilla called Johnny whose criminal father wants him in the family's armed robbery business rather than on a stage, a porcupine named Ash in a bad relationship with a more talented bandmate, and an elephant named Meena who has a world-class voice but crippling stage fright.

The first film was a surprise hit. Critics praised its efficient, unpretentious commitment to delivering exactly what it promised: a colorful, music-filled family movie with genuine emotional warmth. The voice cast was exceptional, and the selection of familiar pop songs was shrewdly chosen to appeal to adults as much as children. By the time it had finished its theatrical run and settled into the home video market, Sing had grossed over a billion dollars worldwide and established itself as one of Illumination's most popular franchises.

Sing 2 arrived five years later with a significantly bigger budget and ambition to match.

A spoiler-free premise

Koala impresario Buster Moon has a dream that outgrows his hometown theater. He and his troupe of singing animals chase a dazzling new show in glittering Redshore City, the entertainment capital where the brightest stars perform. To make their grand vision a reality, the gang must pitch their idea to a ruthless media mogul and somehow deliver on a wildly ambitious promise.

The biggest challenge of all: the show hinges on coaxing a reclusive rock legend back to the stage after years away from the spotlight. As Buster and his friends juggle stage fright, towering expectations, and the pressure of the big city, they each discover what it really takes to shine. It is a story about chasing dreams without losing sight of one another, told through song after unforgettable song.

The voice cast: a remarkable assembly of talent

One of the consistent pleasures of the Sing franchise is its voice cast, which reads more like a concert lineup than a typical animation ensemble.

Matthew McConaughey voices Buster Moon, and he brings an irresistible combination of showman's confidence and genuine warmth. McConaughey has always been good at playing people who believe in themselves with a slightly unhinged intensity, and Buster channels that quality perfectly. His enthusiasm for the impossible is infectious rather than grating because McConaughey makes you feel the sincerity underneath the salesmanship.

Reese Witherspoon returns as Rosita, the housewife pig who discovered her talent in the first film. In the sequel, Rosita faces a new set of anxieties, specifically a terrifying stunt sequence that her character must perform onstage, and Witherspoon navigates the comedy and the vulnerability with the same ease she brings to her best live-action work.

Scarlett Johansson voices Ash, the porcupine musician, and gets some of the film's best musical moments. Johansson has a strong, slightly husky singing voice that suits rock material particularly well, and her character's arc in Sing 2, which involves working through the emotional aftermath of a difficult relationship while stepping further into her artistic potential, is the emotional spine of the film.

The most talked-about casting is Bono, who voices Clay Calloway, the reclusive rock lion whose return to the stage is central to the plot. Bono, as the frontman of U2, is one of the most recognizable rock voices of the past four decades, and the filmmakers use that recognition to give Clay Calloway's reluctance genuine weight. When he finally performs, the sequence is one of the most emotionally effective moments in the film, and Bono's voice carries it with a sincerity that is hard to manufacture.

The supporting cast includes Taron Egerton as Johnny, Nick Kroll as the scheming entertainment mogul, and Pharrell Williams as a dancer who becomes Rosita's partner for the dangerous stunt sequence.

Why Sing 2 works so well for families

Animated musical films for families live or die on the balance between their musical sequences and their dramatic ones. Too much story and children get restless; too much spectacle and there is nothing for adults to hold onto between songs.

Sing 2 handles this balance better than most, and better than the first film in several respects. Each of the major characters has a specific dramatic challenge to overcome, and those challenges are varied enough that different members of a family audience will find different ones relatable. Children respond most strongly to Meena's ongoing struggle with shyness and self-doubt. Adults tend to engage more with Rosita's arc about reclaiming ambitions she set aside for her family, or with Clay Calloway's grief-driven withdrawal from public life.

The musical selections are once again shrewdly curated. Sing 2 leans more heavily on rock and pop classics than the first film, with the setlist functioning almost as its own argument about the universality of popular music across generations. Parents who grew up with certain songs will have a different but equally strong reaction to hearing them sung by animated animals in a dazzling concert venue.

The villain is worth noting too. Nick Kroll's entertainment mogul is a more interesting antagonist than family animation usually produces, a person whose cruelty comes entirely from his contempt for anyone who cannot give him something he wants, rather than from the kind of theatrical evil that animated films often default to. He is recognizable, which makes him funnier and scarier at once.

Related animated musicals to watch next

If Sing 2 has put you in the mood for more animated musical entertainment, the past decade has produced an exceptionally strong slate.

Moana (2016) is Disney's best pure musical of the decade, featuring a Polynesian teenage protagonist on an oceanic quest and a Lin-Manuel Miranda-penned soundtrack that stands with the best work of the Disney Renaissance.

Encanto (2021) won the Academy Award for Best Animated Feature and features another Miranda songbook, this time set in a magical Colombian family where every member has a special gift except the protagonist. The breakout track "We Don't Talk About Bruno" became the most streamed song of 2022.

The Bad Guys (2022) is not a musical in the strict sense but shares Sing 2's colorful, kinetic energy and its enjoyment of the gap between criminal reputation and genuine personality.

Trolls World Tour (2020) is essentially a feature-length meditation on different genres of music with a strong cast and the confidence to be completely, unapologetically silly.

For those who want to go deeper into the Illumination universe specifically, The Super Mario Bros. Movie (2023) and Despicable Me 4 (2024) offer the same studio's house style of relentless visual energy and accessible comedy.
